Reply to ELI5: If drinking salt water further dehydrates the body, why is saline used to treated dehydration? by Dartualexmachina
False premise. Drinking salt water doesn't necessarily dehydrate the body. It's just that to avoid that particular effect, you have to drink much smaller quantities at a time, more consistently over long periods of time.

Those are dissolved solids in mg/L. Did you notice how the top 2 are literally table salt? Potassium Chloride is NuSalt (a type of table salt), Magnesium Chloride is valued in industry, Flouride is valued in industry (especially dental products).
The only things I see in this list that are problematic are the Strontium and the Bromide, and I'm sure somebody has a use for them. This is really just an entrepreneur's opportunity waiting to happen

>Then, what to do with the salty sludge leftover.
Clean it up and sell it as table salt or leave it dirty and sell it as road salt for the winter (of which there is also currently a shortage)

Reply to Eli5 - “Good morning America. It’s 8 a.m. “ by tuff_gong
In order for most people in the world to experience daylight at the same hours on a clock, time zones were invented because the Earth is in different positions relative to the sun at the same actual time (when it's night in New York, it's daytime in Hong Kong, for example). Because people have a hard time accepting that 3pm can be in the middle of the night, we developed time zones. Each time zone is roughly 1/24 of the Earth's circumference wide (at the relevant latitude). So, when you compare noon in New York to noon in Western Indiana, you are both talking the time when the sun is highest in the sky, rather than one of you seeing it slightly lower.

Reply to eli5 Am I cousins with someone? by Mobile-Winner6911
You are not related in any way that can be deduced from the information provided. It's entirely possible that you're, like, 7th-cousins, 14 times removed or something, but without a much more extensive family tree, it's impossible to say that you are related in any way other than by double-marriage (which I'm assuming doesn't count in this scenario)
Edit: correcting an assumption

Reply to Eli5 : is the order of the colors in a real rainbow always the same? and why , whichever it is? by Just_a_happy_artist
Yes, always. Because the frequency of the light is what determines what color it is, and it's the light that's getting separated into its component wavelengths. Each wavelengths "bends" a little more than the one before it (gets diffracted)

Reply to eli5 how names work in the world by Nakakapag_pabagabag
Names and naming conventions differ around the world. Documentation of names differs around the world, too. It's really, really culture specific. For example, the United States (default) is 3 names: given name #1, given name #2, and surname, in that order. But, sometimes there are 4 (looking at the Catholics): given, given, religious, and surname or given, religious, given, surname. In Korea, it's surname, given name (inherited), lucky name (Kim Jong Un's surname is Kim and his given name is Un) In Iceland, it's given name and (parents' given name)-son or given name and (parent's given name)-dottir. So Ezra Emmasdottir or Carl Gustavson (as examples).

Reply to ELI5: How exactly does pirating work for video games and software? (Read desc) by DryEstablishment2
Hacks, cracks, and jacks.
Hacks are tools that allow you to take a straight copy/paste and edit some portion of the code so that a copy check always passes. (Breaking the lock)
Cracks are tools that allow you to use other programs to create codes or keys that will pass any verification check (think of a key-duplicating machine at a hardware store)
Jacks: straight up copies of stuff that doesn't even have a lock on it, or one that's so simple it can be bypassed just by pushing hard enough.
But, everything starts with a straight-up copy/paste of the original software.

You're missing the fact that the recoil is already distributed over a larger area when it impacts the vest (the butt of the weapon has a much larger impact area than the point of the bullet)

Reply to eli5: What are the subtypes of games? by Broyster
Tycoon games are a sub-genre of city-building games. City-building games are a sub-genre of simulation games. I'm not actually sure if there are sub-genres of tycoon games because at that level of fidelity, you get into the actual games themselves, which include, railroad tycoon, sim-ant, Rollercoaster tycoon, airport tycoon, and the like.

So, there's a real problem here with the question itself. A black hole is a thing that can't be seen, bit the effects of a black hole can be seen. So, if the question is "What does a black hole itself look like?" The answer is "nothing. It looks like the absolute and complete absence of all things." If, however, the question is "what would we see if we tried looking at a black hole from a reasonably close, but safe, distance?" It's a little more complicated. Mostly, you'd see a pair of rings at 90 degrees to each other made of the brightest stuff imaginable and separated in your view by areas of the blackest, darkest hemi-circles you can imagine, except the borders of both areas are really, really fuzzy.
Also: black holes, if they had dimensions, would be spheres, and their effects are also spherical (sort of...kinda ellipsoidical, depending on rate of rotation and such, but generally spherical)

Reply to comment by artfellig in Anyone have experience with tiny digital projectors? by artfellig
No, but it was very small. A pocket projector, I think it was called. Black box, about 3 inches long and one inch wide. I was pretty fond of Black Web at the time, so maybe one of theirs... I think I paid about $100 for it at the time...

I don't know about tiny, but there are some reasonably small displays (about 8 inches, using TV measurements), the one I have connected via USB, with separate power cable. Worked great for displaying stuff kinda like a Picture-in-Picture thing.
frustrated_staff t1_j1hgecz wrote
You can get a really small image, really, really close up. I had one of these for a Karaoke thing I used to do, and yes, I wanted to project a large image reasonably far away, but I also had to test the thing before putting on the show. So...got it all hooked up and ready and tested it in my palm. Still looked good and worked great. Very bright. In my palm, the edge of the projector was less than a foot away at filling-my-palm size.

Reply to Eli5: Why can’t Google shut down Anonymous’s YouTube channel or track them and have them arrested? by thefreshlycutgrass
Google (and Alphabet by extension) can shut down their channel. That's easy enough.
As far as having them arrested, well...that's complicated. YouTube hosts servers all over the world, and not everywhere in the world has the same laws, so while Anonymous might be breaking the Las in Iran, for example, if the original poster is in South Africa, they have no agency to perform the arrest. Of course, Google doesn't have arrest power to begin with, but they couldn't even coordinate with local law enforcement. You can't be arrested for something that isn't a crime.
Next comes tracking. After all, you can't arrest someone you can't find, right? But here's the thing. "Channels" belong to individuals. Anonymous is an organization. And its an extremely dispersed organization, at that. More like a social club in terms of hierarchical organization. So, at best, each "track" leads back to one person. Shut down the channel first and you don't even have that. Then, you have to consider VPNs. If the uploaded is using one, they aren't really trackable at all (AFAIK). And given the hacker nature of the group itself, they're probably using custom-built VPNs, so the VPN provider can't help there, either. Then there's masking (assuming you can through the VPN): masking is another way to disguise your location.
And finally, because Anonymous is a group, not an individual, if you reallybwanted to het them all, the whole tracking and coordination aspects would have to be done in complete secrecy right up until the moment doors get kicked in. Assuming 1000 members in 20 countries (a conservative estimate if ever there was one), there's no way to successfully coordinate that and keep it secret. It's just not logistically or politically feasible.
And, in the end, the ultimate question: Why would they even want to try?

Reply to Eli5: How do people get those absolutely gigantic LG TVs in their house after it was built? by PhychologicalEgg
You'd have to be talking about an absolutely massive TV. Like, larger than commercially available (to the general public). Which is, of course, possible, but in general, the people who can afford those TVs have someone else paid to figure out how to get it inside and installed. Also, video-walls are a thing that exist, and they absolutely do come apart in sections. What's the difference, you ask? A TV is a single unit display. A video-wall is a (nearly) seemless series of displays that interconnect to form one gigantic display. And they're modular! (And AFAIK extremely hard to find these days, but were moderately popular 10-20 years ago)

>n December 1998, the IEC addressed such multiple usages and definitions by creating prefixes such as kibi, mebi, gibi, etc., to unambiguously denote powers of 1024.[10] Thus the kibibyte, symbol KiB, represents 210 bytes = 1024 bytes. These prefixes are now part of the IEC 80000-13 standard. The IEC further specified that the kilobyte should only be used to refer to 1000 bytes. The International System of Units restricts the use of the SI prefixes strictly to powers of 10.
For us old timers, this is about as useful as the IAU saying that Pluto is not a planet. They can go f*** themselves

Radio frequency. It's in the name. RAdio Direction and Ranging.
Edit: I stand corrected. I looked it up, and although it may have started with just radio frequencies, it does indeed, now, use multiple frequency ranges, despite still being called radar (I also acknowledge I got the acronym wrong: it is indeed radio direction and ranging)

Reply to Eli5: what is the difference between/the relationship between RNA and DNA? by LumpyEducation2588
The ELI5 answer is that DNA is the architect and RNA is the builder, but to be a little above ELI5. DNA is the blueprint from which everything is copied from or to. RNA is the copy machine. When DNA needs to copied, it's RNA that comes in and attaches to the open DNA molecule (one side only) matching it's pairs to the DNA before moving off. Once in place, bits and pieces attach to the RNA until the DNA strand is complete and BOOM: new DNA.
